摘要
乐山市境内某井场平整形成填方边坡。边坡坡脚井场污水池开挖中,临空面和边坡支挡工程均出现变形破坏。根据变形破坏的分布规律,从场地地形、建筑物分布、边坡特征和原始坡体物质结构方面,分析该边坡变形机理,评价其稳定性影响因素。并采用极限平衡法对边坡的稳定性及下滑推力进行计算。在此基础上,针对性地提出该边坡的工程处治方案,保证后期井场及污水池的作业安全。
Afill slope has occurred in the construction of JS1 well site in Leshan the free surfaces and supporting constructions during the sewage pool constructio City. Deforms a n. Deformation nd failures have occurred at mechanism fecting factors are analyzed in terms of topography, building distribution, slope characteristics and original slope st t stability-af- ructure. The limit equilibrium method is used to calculate the slope stability and the slide-thrust force. Then corresponding engineering measures are proposed to guarantee the security in the late well site and pool construction.
